The
Origins of Gravity:
(For those who thought that Sir Isaac Newton invented gravity,
he was the first to develop a quantitative theory of gravitation.
The story of the falling apple was an symbolic representation
of the effect for the layman.)
"
In the books of philosophers who speculated about the condition
of the world, it has been explained that the earth has a spherical
shape and is enveloped by the element of water. It may be compared
to a grape floating upon water. The water withdrew from certain
parts of the earth, because God wanted to create living beings
upon it and settle it with the human species that rules as His
representative over all other beings. One might from this get
the impression that the water is below the earth. This is not
correct. The natural 'below' of the earth is the core and middle
of its sphere, the centre to which everything is attracted by
its gravity. All the sides of the earth beyond that and the
water surrounding the earth are 'above'. When some part of the
earth is said to be 'below', it is said to be so with reference
to some other region. "
